The fact that his head was spinning was probably equal parts the alcohol and the kiss. Charlie hoped. Any alternative was just embarrassing. His hand slid up, callouses catching in the short hair at the Oliver's nape as he tilted his head a little. It wasn't a brilliant kiss. It probably wasn't even a good kiss. Oliver tasted of beer and the wierd chive and garlic snack things they'd split a packet of earlier; and Charlie probably tasted even worse. Parting his lips slightly, he managed to mash his lower lip against Oliver's teeth, hard enough to sting.
But it still made his knees feel a little watery.
Humming softly, Charlie clutched a handful of the back of Oliver's coat, swaying forward a little as he tried to get closer, his balance off.
